Transcription

1 IP3900 & IS3900 series C ole Instrument Corporation is proud to offer a rotary switch with illumination through the end of the shaft front. This can be used to light up any part of the rotary switch s knob. An LED (Light Emitting Diode) or an incandescent lamp is on the back end of the switch body, and a light pipe or fiber optics brings the concentrated light through the switch to the shaft front. The Series IP3900 and IS3900 switch offers maximum and optimum visibility at sunlight with minimum power levels. And at night, there is zero light leakage through the length of the switch. Light can meet most chromaticity or intensity requirements. The light can be an LED or a T1 incandescent lamp. The switch features good heat sinking capabilities, and delivers up to twice the light intensity of units at equivalent power levels. On light failure, reclamping can be done by the customer. Cole can provide the replacement assembly. This switch can be used in airborne, shipboard, and submarine panel control displays and meets the brightness requirements of high altitude aircraft, as well as the MIL-S-901C shock requirement for submarines and ships.
